Description

Technical Field

[0001] The invention relates to the technical field of cleaning equipment, in particular to a cleaning equipment capable of utilizing the internal pressure of a pressure cooker. Background Art

[0002] A pressure cooker, also known as a pressure cooker, works by cooking without boiling, using the physical property that the boiling point of water is affected by air pressure. Usually, when water is boiled at 1 atmosphere of pressure, it will boil at around 90-105°C. The air pressure in a pressure cooker is generally 1.5 atmospheres, and the boiling point of water is generally around 110-130°C, which can speed up the efficiency of stewing food. In other words, when the pressure cooker is working, a high-temperature and high-pressure environment will be formed inside it. The existing technology generally provides an exhaust valve on the lid of the pressure cooker to discharge the water vapor in the pressure cooker in a timely manner, thereby ensuring that the pressure inside the pressure cooker is maintained within a safe and controllable range. For example, the invention patent with Chinese patent number CN201220749747.3 discloses an exhaust valve assembly for a pressure cooker, the invention patent with Chinese patent number CN201210248802.5 discloses a pressure limiting and overpressure protection device for a pressure cooker, and the invention patent with Chinese patent number CN202222310093.0 discloses a lid for a pressure cooking appliance.

[0003] In addition, the counters, tableware, fruits, etc. in the kitchen all need to be cleaned, so users need to equip the kitchen with a cleaning device, such as a quick kitchen cleaning device for tableware, fruits and vegetables disclosed in the invention patent with Chinese patent number CN202221662719.8.

[0004] However, high-temperature and high-pressure water vapor has certain decontamination, disinfection and cleaning functions, so directly discharging the water vapor in the pressure cooker will cause a waste of resources. If the user equips a cleaning device separately, it will increase the cost of use and take up space in the kitchen. If the cleaning device and the exhaust valve are directly connected using a connecting pipe, the normal connection between the connecting pipe, the cleaning device and the exhaust valve cannot be achieved due to the high pressure, resulting in leakage of high-temperature and high-pressure water vapor, which will still cause a waste of resources. Or during use, the connecting pipe and the cleaning device may loosen and fly off due to the high pressure, and the safety of use is extremely low.

[0005] Therefore, further improvement is necessary. Summary of the Invention

A partition 20 is sealed and fixedly provided inside the connecting seat 1, and a pressure chamber 2 and a pressure relief chamber 31 are separated by the partition 20; a cleaning device connecting port 32 is provided on the side of the pressure chamber 2, which is detachably connected to the cleaning device 33, and a pressure cooker connecting port 3 is provided on the end portion, which is detachably connected to the exhaust pipe 4 on the pressure cooker; a pressure relief port 34 is provided on the side of the pressure relief chamber 31.

[0060] A pressure relief hole 35 is axially arranged on the separator 20; the pressure chamber 2 and the pressure relief chamber 31 are connected to each other through the pressure relief hole 35; a covering member 36 is provided in the pressure relief chamber 31, and the covering member 36 moves according to the pressure limit in the pressure chamber 2, and covers or opens the pressure relief hole 35 when moving, so as to limit the pressure range in the pressure chamber 2.

[0061] A floating member 5 is movably provided on the separator 20 ; a swing member 6 , a limiting member 7 , and a removal member 37 are movably provided on the connecting seat 1 .

[0062] The swinging member 6 and the limiting member 7 are linked to each other and clamp or release the exhaust pipe 4 when moving; the floating member 5 reciprocates according to the pressure in the pressure chamber 2 and abuts against or releases the limiting member 7 when moving, so that the swinging member 6 is positioned on the connecting seat 1 and clamps the exhaust pipe 4 in an anti-slip manner.

[0063] When the removal member 37 is moved, it drives the covering member 36 to open the pressure relief hole 35 , so as to quickly discharge the pressure in the pressure chamber 2 and realize the removal between the connecting seat 1 and the exhaust pipe 4 .

[0064] This embodiment has the following advantages through the improvement of the above structure:

[0065] First, by utilizing the connection between the exhaust pipe 4 and the pressure cooker connecting port 3, the high-temperature and high-pressure water vapor inside the pressure cooker can enter the pressure chamber 2, so that the pressure chamber 2 can store high-temperature and high-pressure water vapor. Then, by connecting the cleaning device 33 with the cleaning device connecting port 32, the user can use the high-temperature and high-pressure water vapor in the pressure chamber 2 for decontamination, disinfection, cleaning, etc. through the cleaning device 33, thereby effectively utilizing the high-temperature and high-pressure water vapor inside the pressure cooker, thereby improving resource utilization, reducing resource waste, and reducing the number of equipment and user costs.

[0066] Second, when the high-temperature and high-pressure water vapor in the pressure chamber 2 reaches the pressure range, the floating member 5 will move in the direction away from the pressure chamber 2 and abut against the limiting member 7, thereby limiting the position of the limiting member 7 and positioning the swing member 6 on the connecting seat 1, so that the swing member 6 cannot swing and the exhaust pipe 4 is clamped in an anti-detachment manner, ensuring that the connection between the pressure cooker connecting port 3 and the exhaust pipe 4 will not be unstable due to excessive pressure in the pressure chamber 2, or the connecting seat 1 will loosen and fly off the exhaust pipe 4. This not only ensures stable assembly between the connecting seat 1 and the exhaust pipe 4, but also ensures that sufficient high-temperature and high-pressure water vapor can be stored inside the pressure chamber 2.

[0067] 3. When the high-temperature and high-pressure water vapor in the pressure chamber 2 exceeds the pressure range, the cover 36 will limit the high-temperature and high-pressure water vapor in the pressure chamber 2 and open the pressure relief hole 35, so that the high-temperature and high-pressure water vapor in the pressure chamber 2 is discharged to the pressure relief chamber 31 through the pressure relief hole 35, and finally discharged from the pressure relief port 34, so as to avoid the safety hazard caused by excessive high-temperature and high-pressure water vapor in the pressure chamber 2, thereby limiting the high-temperature and high-pressure water vapor in the pressure chamber 2 to always remain within a certain pressure range, ensuring the safe use of the cleaning device 33.

[0068] Fourth, the movement of the removal member 37 drives the covering member 36 to open the pressure relief hole 35, so that the high-temperature and high-pressure water vapor in the pressure chamber 2 can be continuously and quickly discharged from the pressure relief hole 35 to the pressure relief chamber 31, and finally discharged from the pressure relief port 34. At the same time, the floating member 5 can also be reset to the initial position and separated from the limiting member 7. The user can then drive the swing member 6 to swing and loosen the exhaust pipe 4, so that the user can safely and quickly remove the connecting seat 1 and the exhaust pipe 4, and the operation is convenient.

[0069] The specific structure of this embodiment is as follows:

[0070] A limiting elastic member 8 is provided on the limiting member 7, and the limiting elastic member 8 is radially elastically movable on the connecting seat 1; an action arm 9 is provided at one end of the swinging member 6; the limiting member 7 is always linked with the action arm 9 through the limiting elastic member 8, and the other end of the swinging member 6 has a side wing 10 extending laterally toward the connecting seat 1, and a clamping opening 11 is provided at the end of the side wing 10, and the swinging member 6 clamps or releases the exhaust pipe 4 through the clamping opening 11; a rotating shaft 12 is also provided on the side wing 10, and the rotating shaft 12 is located between the action arm 9 and the clamping opening 11; the swinging member 6 is swingably set on the connecting seat 1 through the rotating shaft 12.

[0071] In this embodiment, an L-shaped fit is formed between the action arm 9 and the side wing 10, so that the user can drive the side wing 10 simultaneously through the rotating shaft 12 while driving the action arm 9, and the distance between the action arm 9 and the rotating shaft 12 is greater than the distance between the clamp 11 and the rotating shaft 12, so as to increase the action distance of the action arm 9, so that the user can use a smaller force to overcome the elastic force of the limiting elastic member 8 and drive the swing member 6 to swing.

[0072] A radial avoidance groove 14 is provided at the end of the connecting seat 1, and an axial avoidance groove 15 is provided on the side wall; the radial avoidance groove 14 and the axial avoidance groove 15 are communicated with each other; the pressure cooker connecting port 3 is located in the radial avoidance groove 14; the side wing 10 extends into the radial avoidance groove 14; when the action arm 9 swings toward the direction of the connecting seat 1, it avoids the axial avoidance groove 15.

[0073] In this embodiment, since the action arm 9 can avoid the axial avoidance groove 15 and the side wing 10 extends into the radial avoidance groove 14, it can not only increase the compactness of the connection between the components, but also reduce the size of the entire connection device.

[0074] An axial boss 16 is also axially extended on the radial avoidance groove 14. The axial boss 16 is provided with a boss hole connected to the pressure cooker connecting port 3. A boss seal 17 is provided in the boss hole; the exhaust pipe 4 is sealed and connected to the pressure cooker connecting port 3 through the boss seal 17.

[0075] In this embodiment, the boss seal 17 is arranged in the boss hole, thereby improving the assembly stability of the boss seal 17. At the same time, the sealing effect of the boss seal 17 can ensure the sealed connection between the exhaust pipe 4 and the pressure cooker connecting port 3, thereby preventing high-temperature and high-pressure water vapor from leaking through the gap between the exhaust pipe 4 and the pressure cooker connecting port 3.

[0076] A sleeve portion is provided at one end of the limiting member 7, which radially passes through the axial avoidance groove 15 and is fixedly provided with a supporting member 18; the limiting elastic member 8 is sleeved on the sleeve portion, one end of which elastically acts on the supporting member 18, and the other end elastically acts on the axial avoidance groove 15; the supporting member 18 is located outside the axial avoidance groove 15, and is always elastically pressed against the action arm 9 through the elastic force of the limiting elastic member 8; the other end of the limiting member 7 is located in the pressure relief chamber 31, and is in contact with or separated from the floating member 5.

[0077] In this embodiment, the limiting elastic member 8 is a spring and is sleeved on the sleeve portion, so that the limiting elastic member 8 can be stably assembled, avoiding the problem of bending and deformation during operation, and ensuring that an effective elastic force can be generated.

[0078] In this embodiment, the limiting elastic member 8 always generates an elastic force on the supporting member 18, that is, when no external force is generated, the supporting member 18 and the limiting member 7 always elastically move in the direction away from the connecting seat 1 through the limiting elastic member 8, so that the clamp 11 always elastically clamps the exhaust pipe 4.

[0079] The exhaust pipe 4 is provided with a disassembly and assembly tilting position 13 , and the disassembly and assembly tilting position 13 and the clamping opening 11 are clamped or loosened in an inclined manner, thereby improving the clamping or loosening stability between the exhaust pipe 4 and the clamping opening 11 .

[0080] The boss seal 17 is provided with a sealing inclined position 19 corresponding to the disassembly and assembly inclined position 13; the boss seal 17 cooperates with the disassembly and assembly inclined position 13 on the exhaust pipe 4 through the sealing inclined position 19 to form an inclined guide seal, thereby improving the sealing cooperation stability between the boss seal 17 and the exhaust pipe 4.

[0081] The inner wall of the connecting seat 1 is provided with an intracavity thread; the outer wall of the partition 20 is provided with a partition external thread 22 and a partition positioning groove 23; a partition seal 24 is provided on the partition positioning groove 23; the partition 20 is threadedly connected to the intracavity thread through the partition external thread 22, and is sealed with the inner wall of the connecting seat 1 through the partition seal 24.

[0082] In this embodiment, the partition 20 is fixed in the connecting seat 1 by threads, which not only has a simple structure but also has high stability; at the same time, the partition seal 24 is arranged on the partition positioning groove 23, thereby improving the assembly stability of the partition seal 24. After being fixed, the partition 20 is also sealed to the inner wall of the connecting seat 1 by the partition seal 24 to prevent high-temperature and high-pressure water vapor from leaking from the gap between the partition 20 and the inner wall of the connecting seat 1.

[0083] A partition through-hole 21 is also axially provided on the partition 20, and there are two partition through-holes 21, which are symmetrical to the outside of the pressure relief hole 35; the floating member 5 is also provided with two corresponding partition through-holes 21; a positioning step 25 is provided in the middle of the floating member 5, and a floating portion 38 is provided at one end of the floating member 5. The floating portion 38 is passed through the partition through-hole 21, and a floating positioning groove 26 is provided at its end. The floating positioning groove 26 is located in the pressure chamber 2, and a floating seal 27 is provided thereon; a distance is formed between the positioning step 25 and the floating seal 27; a resistance portion 28 is provided at the other end of the floating member 5, and the resistance portion 28 is located in the pressure relief chamber 31.

[0084] The floating member 5 reciprocates on the partition through hole 21 via the floating portion 38 according to the pressure in the pressure chamber 2 .

[0085] Among them, when the floating part 5 moves toward the direction of the pressure chamber 2, it is limited on the partition through hole 21 by the positioning step 25. At this time, the interference part 28 and the limiting part 7 are separated from each other, and the swinging part 6 elastically swings on the connecting seat 1 through the limiting elastic part 8, and clamps or releases the exhaust pipe 4.

[0086] When the floating member 5 moves in the direction away from the pressure chamber 2, it is sealed and limited on the partition through hole 21 by the floating seal 27. At this time, the contact portion 28 and the limiting member 7 are in contact with each other. When the limiting member 7 and the contact portion 28 are in contact with each other, they are positioned on the connecting seat 1. The swinging member 6 follows the limiting member 7 to be positioned on the connecting seat 1 and clamps the exhaust pipe 4 in an anti-slip manner.

[0087] In this embodiment, the floating seal 27 is arranged on the floating positioning groove 26, thereby improving the assembly stability of the floating seal 27, and the floating member 5 can dynamically seal the sealing member 27 on the partition hole 21 to prevent high-temperature and high-pressure water vapor from leaking from the gap between the floating member 5 and the partition hole 21.

[0088] In this embodiment, the floating member 5 moves toward the pressure chamber 2 by its own weight and the gravity of the floating seal 27 in a state without external force, and is limited to the partition through hole 21 by the positioning step 25. At this time, the floating member 5 and the limiting member 7 are open to each other, and the user can use tools or manually act on the action arm 9, so that the swing member 6 swings and the clamp 11 opens to make way for the pressure cooker connecting port 3, and the exhaust pipe 4 can be assembled on the connecting seat 1 from the clamp 11 and pass through the pressure cooker connecting port 3; or drive the connecting seat 1 to move toward the exhaust pipe 4, so that the exhaust pipe 4 acts on the clamp 11 through the disassembly and assembly tilt position 13, so that the swing member 6 overcomes the elastic force of the limiting elastic member 8, and makes the clamp 11 open to make way for the pressure cooker connecting port 3, and the exhaust pipe 4 can be assembled on the connecting seat 1 from the clamp 11 and pass through the pressure cooker connecting port 3.

[0089] When the high-temperature and high-pressure water vapor in the pressure chamber 2 reaches a certain pressure, these pressures will drive the floating part 5 to move in the direction away from the pressure chamber 2. At the same time, the floating part 5 is sealed and limited on the partition through hole 21 by the floating seal 27 to prevent the high-temperature and high-pressure water vapor in the pressure chamber 2 from leaking out. At this time, the resistance part 28 and the limiting part 7 abut against each other, so that the swinging part 6 is positioned on the connecting seat 1. At the same time, the swinging part 6 cannot swing and clamps the exhaust pipe 4 in an anti-detachment manner, so that sufficient high-temperature and high-pressure water vapor is stored in the pressure chamber 2 for user use.

[0090] An interfering inclined position 29 is provided between the interfering portion 28 and the limiting member 7 , and the two are inclinedly guided to abut or separate through the interfering inclined position 29 , thereby improving the abutment or separation stability between the limiting member 7 and the floating member 5 .

[0091] The covering member 36 is a ball, and rolls according to the pressure in the pressure chamber 2 , and covers or opens the pressure relief hole 35 .

[0092] A floating through hole 39 is radially provided on the outer wall of the floating portion 38 ; a floating through hole 40 is axially provided on the end of the floating member 5 facing the pressure relief chamber 31 , and the floating through hole 40 is communicated with the floating through hole 39 .

[0093] The floating through hole 39 is located in the pressure chamber 2 when the positioning step 25 and the separating through hole 21 are limited and matched. The high-temperature and high-pressure water vapor in the pressure chamber 2 can enter the pressure relief chamber 31 through the floating through hole 39 and the floating through hole 40.

[0094] The floating through hole 39 is located in the partition through hole 21 when the floating seal 27 and the partition through hole 21 are in sealing and limiting cooperation, so as to prevent the high-temperature and high-pressure water vapor in the pressure chamber 2 from being discharged outward.

[0095] In this embodiment, the force driving the movement of the floating member 5 is less than the force driving the movement of the cover 36. When the pressure chamber 2 contains relatively low levels of high-temperature, high-pressure steam, the floating member 5 is driven away from the chamber 2. When the high-temperature, high-pressure steam in the chamber 2 exceeds the pressure range, the cover 36 moves to open the pressure relief hole 35.

[0096] In this embodiment, after the cover 36 opens the pressure relief hole 35, the high-temperature and high-pressure water vapor in the pressure chamber 2 is discharged from the pressure relief hole 35 to the pressure relief chamber 31. At this time, the air pressure in the pressure chamber 2 is reduced, and the floating member 5 is reset toward the direction of the pressure chamber 2. The floating through hole 39 and the floating through hole 40 enter the pressure relief chamber 31, and the high-temperature and high-pressure water vapor in the pressure chamber 2 is also discharged from the floating through hole 39 and the floating through hole 40 to the pressure relief chamber 31, thereby quickly realizing the pressure relief in the pressure chamber 2, allowing the user to quickly, conveniently and efficiently complete the removal between the connecting seat 1 and the exhaust pipe 4.

[0097] An arc-shaped recess 41 is provided at the end of the pressure relief hole 35 facing the pressure relief chamber 31; an extension rod 42 is provided at one end of the removal piece 37, the extension rod 42 is located in the pressure relief chamber 31, and a toggle portion 43 and a limiting portion 44 are provided thereon; the extension rod 42 is arranged on the same axis as the pressure relief hole 35; the toggle portion 43 is arranged close to the axis of the pressure relief hole 35; the limiting portion 44 is arranged away from the axis of the pressure relief hole 35; the toggle portion 43 and the limiting portion 44 are arranged opposite to each other, and a lateral activity area 45 is formed between the two; a limiting area 46 is formed between the two floating parts 5.

[0098] In this embodiment, the extension rod 42 is arranged on the same axis as the pressure relief hole 35, the axis of the toggle portion 43 is close to the axis of the pressure relief hole 35, and the axis of the limiting portion 44 is away from the axis of the pressure relief hole 35. Therefore, the movable position of the cover 36 can be effectively limited, so that the cover 36 can only move in a single direction in the pressure relief chamber 31 and cannot move at will, thereby ensuring that the pressure relief hole 35 is covered or opened.

[0099] In this embodiment, the toggle portion 43 and the limiting portion 44 are offset from the axis of the pressure relief hole 35, so that the toggle portion 43 can be relatively close to the cover 36 and limit one position of the cover 36 in the Y-axis direction, thereby further enabling the cover 36 to move in a specified position and direction.

[0100] The covering member 36 is limited by the limiting area 46 and moves in a limited manner along a single direction within the lateral movable area 45 .

[0101] In this embodiment, the covering member 36 is placed in the space between the lateral movable area 45 and the limiting area 46 , and the covering member 36 can only move in a single direction between the toggle portion 43 and the limiting portion 44 .

[0102] When the pressure in the pressure chamber 2 is within a limited range, or the removal member 37 moves in a direction away from the connecting seat 1 , the covering member 36 covers the pressure relief hole 35 through the arc-shaped recess 41 by its own weight.

[0103] That is, in normal use, the cover 36 can adaptively cover the pressure relief hole 35 through the arc-shaped recess 41. Figure 12 or Figure 15 shown.

[0104] When the pressure in the pressure chamber 2 exceeds the specified range, the covering member 36 moves in a limited direction in the lateral movable area 45 through the pressure in the pressure chamber 2 and is positioned on the limiting portion 44 to open the pressure relief hole 35, and / or, when the removal member 37 moves toward the direction of the connecting seat 1, the removal member 37 drives the covering member 36 to move in a limited direction in the lateral movable area 45 through the toggle portion 43 and is positioned on the limiting portion 44 to open the pressure relief hole 35.

[0105] That is, when the pressure in the pressure chamber 2 exceeds the specified range, the cover 36 will move laterally in one direction and open the pressure relief hole 35, and the high-temperature and high-pressure water vapor in the pressure chamber 2 will enter the pressure relief chamber 31 from the pressure relief hole 35, and finally be discharged from the pressure relief port 34, so as to avoid excessive high-temperature and high-pressure water vapor in the pressure chamber 2; or, when the user needs to remove the connecting device and the cleaning device 33, the removal member 37 can be driven by the toggle portion 43 to drive the cover 36 to move laterally in one direction and open the pressure relief hole 35, and the high-temperature and high-pressure water vapor in the pressure chamber 2 will enter the pressure relief chamber 31 from the pressure relief hole 35, and finally be discharged from the pressure relief port 34, thereby quickly discharging the high-temperature and high-pressure water vapor and realizing the removal between the connecting device and the cleaning device 33. Figure 14 or Figure 16 shown.

[0106] In this embodiment, the toggle portion 43 is provided with a guiding portion 70 corresponding to the cover 36. The toggle portion 43 drives the cover 36 through the guiding action of the guiding portion 70, thereby improving the driving stability between the toggle portion 43 and the cover 36 and avoiding jamming.

[0107] An opening 47 is provided at the end of the pressure relief chamber 31, and a cover plate 48 is sealed and fixed on the opening 47, a socket 49 is fixed on the cover plate 48, and a transition elastic member 50 is provided between the socket 49 and the cover plate 48; the cover plate 48 and the socket 49 are respectively axially provided with corresponding cover plate assembly holes 51 and transition assembly holes 52; the other end of the removal part 37 is provided with a pressing part 53, and the pressing part 53 extends out of the pressure relief chamber 31 through the transition assembly hole 52 and the cover plate assembly hole 51.

[0108] The removal member 37 is elastically movable in a direction away from the connecting seat 1 at all times by the elastic force of the adapter elastic member 50 .

[0109] The removal member 37 is moved toward the connecting seat 1 by being pressed by the pressing portion 53 .

[0110] In this embodiment, when no external force is generated, the two upper floating parts 5 can limit the X-axis position of the covering part 36, and the toggle part 43 and the limiting part 44 respectively leave the covering part 36. The covering part 36 can only perform unidirectional movement in the Y-axis direction within the lateral activity area 45 between the toggle part 43 and the limiting part 44.

[0111] Since the covering member 36 can only perform a unidirectional limiting movement, the covering member 36 can move in a specified position and direction, and ensure that the pressure relief hole 35 is effectively opened or covered.

[0112] The outer wall of the cover plate 48 is provided with a cover plate thread 54 and a cover plate positioning groove 55, and a cover plate boss 56 is provided on the inner top; a cover plate seal 57 is provided on the cover plate positioning groove 55; the outer wall of the cover plate boss 56 is provided with a boss thread 58; the cover plate assembly hole 51 axially passes through the cover plate boss 56; the inner wall of the opening portion 47 is provided with an opening thread 59; the inner wall of the socket 49 is provided with a transition thread 60; the outer wall of the pressing portion 53 is provided with a side ring 61, the side ring 61 is provided with a side ring positioning groove 62, and the side ring positioning groove 62 is provided with a side ring seal 63.

[0113] The sleeve 49 is threadably connected to the boss thread 58 via an adapter thread 60 .

[0114] The cover plate 48 is threadedly connected to the opening thread 59 via the cover plate thread 54 and is sealed with the opening portion 47 via the cover plate seal 57 .

[0115] In this embodiment, the cover seal 57 is arranged on the cover positioning groove 55, thereby improving the assembly stability of the cover seal 57. At the same time, the sealing effect of the cover seal 57 can ensure the sealing connection effect between the connecting seat 1 and the cover 48.

[0116] At the same time, the side ring seal 63 is arranged on the side ring positioning groove 62, thereby improving the assembly stability of the side ring seal 63. At the same time, the sealing effect of the side ring seal 63 can ensure the sealing connection between the cover plate 48 and the removal part 37, thereby preventing the removal part 37 from leaking high-temperature and high-pressure water vapor in the gap between the cover plate 48 and the removal part 37 when the removal part 37 is moving.

[0117] In this embodiment, the connecting seat 1 and the cover plate 48, and the cover plate 48 and the socket 49 are directly fixed by threads, respectively. The structure is simple, the stability is high, and the disassembly and assembly are convenient.

[0118] The transition elastic member 50 is sleeved in the cover plate assembly hole 51, one end of which elastically acts on the sleeve member 49, and the other end elastically acts on the side ring 61; the removal member 37 is elastically movable in the cover plate assembly hole 51 through the coordinated sealed limiting of the transition elastic member 50, the side ring 61, and the side ring seal 63.

[0119] In this embodiment, the transition elastic member 50 is a spring, which is set in the cover assembly hole 51 in a sleeve manner, so that the transition elastic member 50 can be assembled stably, avoiding the problem of bending and deformation during operation, and ensuring that an effective elastic force can be generated.

[0120] In this embodiment, when the cleaning device 33, the connecting seat 1, and the exhaust pipe 4 are assembled, the high-temperature and high-pressure water vapor in the pressure cooker will enter the pressure chamber 2 and then enter the cleaning device 33. The user can use the high-temperature and high-pressure water vapor in the cleaning device 33 to clean oil stains or other stubborn dirt on the kitchen range hood, refrigerator, kitchen corners and certain places in the home.
